To all fio/tom it may concern: respective slots. Each hammer is drawn Be it known that l, HENRY Hermien, of outward by a spring Q4 that is secured to a New York city, in the county of New York pin 25 in the plate 23, the spring engaging and in the State oi' New York, have invented the pin QG secured in the hammer, the latter oo a certain new and useful lmprovement in pin projecting through a slot 27 in the plate. b1waging-Iriachines, and do hereby declare rEhe outer surface oi' the annular frame is that the following is a full, clear, and exact conical, and the outer ends or the hammers description thereof, reference being had to are correspondingly formed, so that when the accompanying drawings, in whichthe inner` conical surface 2S of ring 29 is 65 Figure l is a side elevation of a machine 'forced rearward, it causes said hammers to embodying my invention; F ig. 2 is a vertimove toward the center into position to be cal, central, longitudinal sect-ion or Fig. l; struck by the swaging tools as each tool and Fig. 3 is a transverse sectional view of passes a hammer. s a convenient means of Fig. l, in the plane of the swaging tools. forcing the ring 29 rearward, a screwthread 70 rihe object of my invention has been to '50 on the said ring engages a screw-thread provide a swaging machine which, while 3l on the annular frame, so that upon rotatspecially adapted for swaging iinger-rings, ing the ring 2S, the said action will be shall be capable of other uses, and in which effected. the work can be readily inserted; and to in order to open the swaging tools, so 75 such ends my invention consists in the swagthat a piece of work may be inserted, the ing machine hereinafter specilied. following arrangement is provided: A sleeve ln carrying my invention into practice, I 3Q is mounted in the spindle l0 so as to be pl-Gvd@ L hQUOW @indie 10 mounted in gue longitudinally movable, and the forward able bearings, and suitably driven. @n the end or" the said sleeve is beveled or provided 8O forward end of said spindle is a head 11 in with a conical surface. The inner rear con which are swaging toolg l2, mount-@d in ners et the swaging tools are beveled to proradially formed slots. A plate 13 which vde shoulders to cooperate with said consegui-ed 'to the head 11 in my approved manical surface, and thus, when the sleeve is nel' g1g by Screw/'S Covers the 01357 and 599111165 ZOlCQd fOlWHl, .lS COTllCll SUl'lilC-( SllglgS S5 the toolg in place, The @01S am normally the beveled corners of the swaging tools and held close together by springs let which are Spreads them apart. secured to pins l5 on the plate 18, and which in lll@ Operation of my machine, for the engage pins 1.6 on the svaging tools, said making of linger-rings, a tube of the pins extending through Slots 17 in the plat@ metal from which the rings are to be inode 90 The swae'ing Vtools l2 are shaped aecordis passed over a mandrel 234i; the sleeve is ing to the work to be done. For forming forced forward to separate the swag-ing {ingelnyin-g, they are pyoeied with Seieg tools, and the tube b3 and mandrel are of grooves 18 which, from Idie front toward inserted between the swaging tools. ln orthe rear, gradually change from the form of der t0 permit the Swoging tools to Spread 95 the tube to the final forni of the finished apart, it is, of course, necessary that the giftigle, until the jrggmnogb groove 0f the llllgf 29 be HDSClWQCl SO that lS COl'llCill S1111* shape which it is desired the inished ringface shall partly or wholly withdraw from blank to have. rihe head ll. is surrounded over the hammers7 to permit the hammers by an annular' frame lf) that is tiXedly seto spread apart, if the swaging tools happen W0 cured to the frame or" the machine. rihe to be .in line with them. rEhe tube S3 is only annular frame is provided with radial slots inserted far enough so that it can be enpreferably of a number equal to a multiple gaged by the first groove in the swaging of the number of swaging tools, and in each tools. The ring QD is then screwed up unt-il slot is mounted a slide 20, 'which will be the hammer causes the swaging tools to 105 termed a hammer. Each slide has a cylinform an impression of the desired depth drical seat 2l formed in its hammer-end, and Where the iirst i'inger-ring blank is to be. a roll 22 is mounted in said sea-t. [i plate rihe rotation of the swaging tools with the 23 which is secured to the annular frame 19 rapid blows which they apply to the metal in any approved manner, as by screws, for being shaped, owing to the action of the H0 example, covers the open ends of the slot-s hammers, causes a very even and rapid acand holds the hammers in place in their tion of the tools on the metal being shaped.

Vhen the lirstgroove of the svvaging tools has completed its Work, the tube 33 being maintained in position therein by the springs lll, the tools are separated again by advancing the sleeve 82, and retracting the ring 29, and the tube is inserted until it is engaged both by the first and second grooves in. the sivaging tools. This operation is repeated until the first linger-ring blank on the tube 33 has passed successively through all the finger-ring forming grooves, when the blank will have been completed. The completed blank can either be severed from the tube 83, or can be passed on into the hollow spindle 10 until the entire tube has been formed into blanks.

lVhile I have described What I consider to be the best embodiment of my invention, I desire it to be understood thatI the principles can be embodied in different forms, and I desire not to be limited beyond the requirements of the prior art, and the terms of my claims.

Having thus described my invention, I claiml. In a svvaging machine, the combination of a rotatable head having sivaging tools mounted therein, means for causing the tools normally to contact- With the Work, means for causing said tools to strike upon the Work, and means vvhereby said tools may be spread apart, for introducing or removing the Work. n

2. In a swaging machine, the combination of a rotatable head provided ivith a series of radial slots, swaging tools mounted in said slots, springs normally tending to force said tools toward the center, means for striking said tools, and means for spreading said tools apart.

3. In a swvaging machine, the combination of a rotatable head having radial slots, swaging tools mounted in said slots, a hollovf spindle upon whichl said head is mounted, and a sleeve mounted in said spindle and provided with a conical end that is adapted to engage and separate said tools.

il. In a svvaging machine, the combination of a rotatable hollow spindle, a head mounted thereon, swaging tools mounted in radial slots in said head, springs tending to force said tools toward the center, a sleeve mounted in said'spindle and provided With beveled end that is adapted to engage beveled shoulders on said tools to spread them apart, an annular frame surrounding said head and provided with dial slots, hammers mounted in said slots, the outer ends of sa-id hammers being beveled, and a ring having an inner conical surface adapted to engage said hammers and force said hammers toward the center.

5. In a sivaging machine, the combination of a rotatable hollow spindle, a head mounted thereon, sivaging tools mounted in radial slots in said head, springs tending to force said tools toward the center, a sleeve mounted in said spindle and provided with a beveled end that is adapted to engage beveled shoulders on said tools to spread them apart', an annular frame surrounding said head and provided With radial slots,

hammers mounted in said slots, the outer ends of said hammers being beveled, and a ring having an inner conical surface adapted to engage said hammers and force said hammers toward the center, said sleeve and annular frame being provided With screwthreads whereby said conical surface can be forced against said hammers.

G. In a swaging machine, the combination of a rotatable hollow spindle, a head mounted thereon, sWaging tools mounted in radial slots in said head, springs tending to force said tools toward the center, a sleeve mounted in said spindle and provided with a beveled end that is adapted to engage beveled shoulders en said tools to spread them apart, an annular frame surrounding said head and provided With radial slots, hammers mounted in said slots, the outer ends of said hammers being beveled, springs tending' to force said hammers outward, and a ring having an inner conical surface adapted to engage said hammers and force said hammers toward the center.

7. In a suaging machine, the combination of a head having a series of svvaging tools radially movable thereon, said tools together forming annular grooves in a progressive series from a shape only slightly different from cylindrical to the final shape of the outer surface of a finger ring, and all of the svvaging tools located upon the head being adapted to be projected against the Work simultaneously.

In testimony that I claim the foregoing I have hereunto set my hand.
